I love the geometry of a wedge heel. Especially in the season's crop of wedge heel boots sans a platform at the toe. The look is sleek, slightly tough, very leg -lengthening and aerodynamic. The walkability factor is a biggie too. Move comfortably all day long in this style. There is a decidedly kitten-with-a-whip quality to over-the-knee styles. If you go there opt for a simple and lightly adorned or textured pair to avoid appearing in your own costume drama.
